The flexible ditopic ligand 1,3-bis[5-(2-pyrimidinyl)-1,2,4-triazol-3-yl]propane H 2 L displays remarkable versatility in the coordination mode depending on the counter anion. With copper(II) nitrate H 2 L acts as a tetradentate chelate forming a mononuclear complex. The reaction with copper(II) perchlorate gives a centrosymmetric dinuclear complex coordinating the deprotonated form...
The reaction of 3-(pyridin-2-yl)-5-(2-aminophenyl)-1H-1,2,4-triazole and salicylaldehyde or benzaldehyde leads a new type of 1,2,4-triazole’s derivats. Reactions of these ligands with zinc acetate in ethanol lead to the formation of two new complexes with azomethine or dihydrotriazaindolizine form of ligands. The structures of these complexes were investigated by X-ray analysis. The complexes showed...
